Abstract

Appareil de levage muni d'un système de sécurité. Il comprend des moyens de levage secondaires solidaires d'une part, de l'organe de préhension et, d'autre part, d'un organe d'entraînement à vitesse variable muni d'un frein. On mesure l'effort appliqué aux moyens de levage secondaires et on le compare à des seuils maximum et minimum On asservit la vitesse des moyens d'entraînement pour que l'effort mesuré, lorsqu'il est compris entre les deux seuils, soit ramené à sa valeur moyenne. On commande le freinage si la mesure devient supérieure au seuil maximal. Application à la réalisation de ponts roulants pour charges élevées.
